At the height of the solar cycle, the Sun is finally displaying some fireworks. This image from the Solar and Heliospheric Observatory (SOHO) shows a large solar flare from June 6, 2000 at 1424 Universal Time (10:24 AM Eastern Daylight Savings Time). Associated with the flare was a coronal mass ejection that sent a wave of fast moving charged particles straight towards Earth. (The image was acquired by the Extreme ultraviolet Imaging Telescope (EIT), one of 12 instruments aboard SOHO) Solar...

At 10:40 UTC on September 24, 2001, a large solar flare erupted from the surface of the sun. Pointed almost directly towards the Earth, the flare caused a coronal mass ejection (CME). Coronal mass ejections are composed of fast-moving clouds of ionized gas. These energetic particles can interfere with wireless communications, damage satellites, disrupt the transmission of electricity, and energize the Earth's upper atmosphere, causing auroras. The images above show several views of the solar... Topics: What -- Sun, What -- Earth, What -- FAST, What -- SOHO, What -- Extreme Ultraviolet Imaging...
